93 octane with 10% ethanol VS 91 octane ethanol-free?

This question is causing a lot of controversy on the Facebook forums. Where I’m at, 93 is hard to find and always has 10% ethanol. 91 without ethanol is everywhere.

What should we be putting in our cars? I’ve only been running the 93, but a lot of people are saying the 10% ethanol will cause issues down the line. Others are saying it’s fine and still preferred over the 91 ethanol-free.

I’ve had this car for 3 days now, and I think I’m obsessed already. Any free time I’ve got, I’m getting inside her.
